deleting sparse bundle files from and Airport Time Capsule

With the last several new operating systems, trying to delete a sparsebundle file using the Finder is next to impossible. Errors that we have never seen before now occur. It seems as if Apple now expects you to erase the Time Capsule disk to delete sparsebundles.

If you need to preserve one or more of the sparsebundle files, you can use the Finder to copy the sparsebundle over to a USB drive attached to the USB port on the Time Capsule.....before.....you erase the Time Capsule disk.

Edit.......you might want to look over this article, but I cannot say whether it will work for you.
